Apprentice 3 2-Pole Relay Board

Model: AP3-2PR

The 2 Pole Relay (AP3-2PR) Board mounts directly in Apprentice 3 lighting control panels and is designed to control 208/240/480 VAC loads. This two pole relay assembly mounts directly in place of the 1PR single pole relay board. The relays are electrically held, are available in N.O. (normally open) contacts, and can be mixed in the lighting controller with1PR relay boards. These relay boards are easily mounted in the Apprentice 3 panel with a push-on connector interface and a single screw.
